Nairn: walls, weather and approvals
We cover Nairn and nearby Forres, Inverness and Elgin. It's roughly 15 miles from Nairn to Inverness, the largest town in Highland. The Highlands and Islands have many exposed stone and harled homes, timber-framed houses and scattered rural properties.
Parts of Highland fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
Whole-house jobs and single elevations are both quoted in Nairn; a cold gable or rear wall can be done on its own where it suits.

Permissions in Scotland
Scottish householder rules mean many Nairn jobs that change the outside of a house need a planning application; we confirm the position before quoting.
Where a building warrant is needed for Nairn work, it's obtained before installation starts, and the quote says who arranges it.
What finish can I have?
Most EWI is finished in a thin-coat silicone render in a through-coloured shade, with a 1–2mm grain. Acrylic, mineral (painted), dry-dash and brick-slip finishes are also available. Where planning wants a brick look, brick slips over the insulation keep the street appearance.

External wall insulation in Nairn: questions
Does external wall insulation cause damp?
Not when it is specified and detailed properly. Problems usually come from poor detailing: no starter track above the damp-proof course, gaps at cills and penetrations, or a vapour-closed system on a wall that needs to breathe. The survey checks moisture, ground levels and the wall type before a system is chosen.
Can EWI go over pebble dash?
Usually yes. The dash is tested for adhesion and hollow areas; sound dash can be insulated over with additional mechanical fixings, while loose areas are removed first.
How long does external wall insulation last?
A well-installed render system is commonly expected to last 25–30 years or more, with occasional cleaning and inspection of sealants. The system manufacturer's documentation states the expected service life for the specific build-up.
